In a tribute to Joe Strummer and The Clash, Dave Grohl, Elvis Costello, Bruce Springsteen and Steve Van Zandt got together at The Grammy Awards in 2003 to perform The Clash’s “London Calling.” Pete Thomas joined them on drums and No Doubt’s Tony Kanal is also there playing bass. It’s a pretty incredible performance.

It also created the inevitable flame war in the YouTube comments, with some youngsters taking shots at “dad rock” some punk fans expressing outrage that traditional rockers like Springsteen would cover The Clash. More knowledgeable fans then pointed out that Joe Strummer always admired Bruce, and once said, “Bruce is great. If you don’t agree with that, you’re a pretentious martian.”
